I was minding my own business, trying to sleep during a presentation at a marketing conference, and was abruptly awakened when the presenter said something like, "to prevent those people from receiving this email, you would disclude them on this screen." The meaning was pretty clear by the context, but it was a word I'd never heard before, and one that just didn't sound quite right. I tried to look it up to confirm.
Dictionary.com? Nope. Apple's dictionary app? Nope. Urbandictionary? Yes, but not so helpful (and more than a bit rude) Wictionary? Bingo. Disclude, as you might guess, means "exclude" and also, as you might not guess, "disclose, make known." Both are listed as "nonstandard" with no "standard" definitions available.
Maybe it was a typo or random error. Maybe I witnessed the birth of a new word or at least of a new meaning. Such is the beauty of English, the language that gives us pairs of synonyms like flammable and inflammable. Feel free to disclude your thoughts in the comments below.
